Background Quantitative coronary angiography (QCA) has inherent limitations for displaying complex vascular anatomy, yet it remains the gold standard for stenosis quantification. Objective To investigate the accuracy of stenosis assessment by multi-detector computed tomography (MDCT) and QCA compared to known dimensions. Methods Nineteen acrylic coronary vessel phantoms with precisely drilled stenoses of mild (25%), moderate (50%) and severe (75%) grade were studied with 64-slice MDCT and… 
Contemporary Discrepancies of Stenosis Assessment by Computed Tomography and Invasive Coronary Angiography: Analysis of the CORE320 International Study
TLDR
Both CTA and ICA perform similarly for predicting clinically driven revascularization and for detecting myocardial ischemia by myocardian perfusion imaging using single-photon emission computed tomography, suggesting that limitations by both CTAand ICA contribute to variability of stenosis quantification.
Quantification of uncertainty in the assessment of coronary plaque in CCTA through a dynamic cardiac phantom and 3D-printed plaque model
TLDR
Results demonstrate successful implementation of a base cardiac phantom with a 3D-printed coronary plaque model, relevant motion profile, and coordinated ECG waveform and show the utility of the model to ascertain metrics of CCTA accuracy and image quality under realistic plaque, motion, and acquisition conditions.
Quantification of the uncertainty in coronary CTA plaque measurements using dynamic cardiac phantom and 3D-printed plaque models
TLDR
Results demonstrate successful implementation of the base cardiac phantom with 3D-printed coronary plaque models, adjustable motion profiles, and coordinated ECG waveforms and show the utility of the model to ascertain metrics of coronary CT accuracy and image quality under a variety of plaque, motion, and acquisition conditions.
Quantitative analysis of coronary artery from computed tomography angiography images
TLDR
An automated, robust and efficient method to approach most Computed Tomography Angiography (CTA) images is still in demand due to the intrinsic ill-posedness and the external stenosis quantification difficulties such as manual.
Quantitative coronary arterial stenosis assessment by multidetector CT and invasive coronary angiography for identifying patients with myocardial perfusion abnormalities
TLDR
Coronary artery stenosis assessment by QCTA or QCA only modestly predicts the presence and the absence of myocardial perfusion abnormalities by SPECT, which may account for some of the observed discrepancies between coronary angiography and SPECT results.
The effect of heart rate on coronary plaque measurements in 320-row coronary CT angiography
TLDR
FIRST may improve plaque measurement repeatability at the higher HR compared with FBP and AIDR3D, and model-based iterative reconstruction (FIRST) might improve plaque measurements repeatability in coronary CTA.
Coronary CT Angiography-derived Fractional Flow Reserve.
TLDR
Improved therapeutic guidance has been demonstrated, showing the potential of FFRCT to streamline and rationalize the care of patients suspected of having CAD and improve outcomes while reducing overall health care costs.
The Relationship Between Absence Coronary Artery Calcification and Myocardial Perfusion Single Photon Emission Computed Tomography
TLDR
Zero CACS in stable patients with low or intermediate risk indicated very low likelihood of obstructive CAD, less than 1%.

Detection of Coronary Artery Stenoses With Thin-Slice Multi-Detector Row Spiral Computed Tomography and Multiplanar Reconstruction
TLDR
MDCT coronary angiography with improved spatial resolution and premedication with oral &bgr;-blockade permits detection of coronary artery stenoses with high accuracy and a low rate of unevaluable arteries.
Accuracy of 16-row multidetector computed tomography for the assessment of coronary artery stenosis.
TLDR
The results of this study indicate that MDCT coronary angiography performed with 16-row scanners is limited by a high number of nonevaluable cases and a high false-positive rate.
Comparative validation of quantitative coronary angiography systems. Results and implications from a multicenter study using a standardized approach.
TLDR
The range of accuracy, intercept, and slope values of this report indicates that absolute measurements of luminal diameter from different multicenter angiographic trials may not be directly comparable and additionally suggests that such absolute measurements mayNot be directly applicable to clinical practice using an on-line QCA system with a different edge detection algorithm.
Diagnostic performance of coronary angiography by 64-row CT.
TLDR
Multidetector CT angiography accurately identifies the presence and severity of obstructive coronary artery disease and subsequent revascularization in symptomatic patients, and the negative and positive predictive values indicate that multidetctor CTAngiography cannot replace conventional coronary angiographic at present.
Coronary disease morphology and distribution determined by quantitative angiography and intravascular ultrasound--re-evaluation in a cooperative multicenter intravascular ultrasound study (COMIUS).
TLDR
It is demonstrated that coronary angiography significantly misinterprets disease morphology in terms of severity, eccentricity and length, in part because of vessel remodeling that can be accurately determined only by IVUS.
Comparison of Intravascular Ultrasound and Quantitative Coronary Angiography for the Assessment of Coronary Artery Disease Progression
TLDR
Although the change in percent atheroma volume is only weakly correlated with QCA changes as continuous variables, disease progression on QCA is associated with significant increases in plaque volume on IVUS compared with no angiographic progression.
Meta-analysis of 40- and 64-MDCT angiography for assessing coronary artery stenosis.
TLDR
Forty- and 64-MDCT provide good-to-excellent performance in detecting or ruling out significant coronary artery stenosis, with better results for proximal than for distal coronary artery segments.
